Real-Time Evaluation of Transceiver Performance with Joint Pre- and Post-Optical Equalization for Passband Narrowing Using 500-Gbps Transmission

We propose a transceiver configuration with optical pre- and post-equalization for channel distortion and show that the configuration enhances the performance of 500- Gbps/lambda PDM-32QAM real-time transmission and frequency-offset tolerance under a severe bandwidth limitation.
